An Ethernet physical layer (PHY) transceiver includes a transmitter and a receiver. The transmitter is configured to precode a first data stream by summing two or more mutually-delayed replicas of the first data stream, and to transmit the precoded first data stream over a full-duplex wired channel to a peer Ethernet PHY transceiver. The receiver is configured to receive a second data stream from the peer Ethernet PHY transceiver over the full-duplex wired channel, and to decode the received second data stream while the transmitter concurrently is transmitting the precoded first data stream.
